Class Overview
Interface for AbstractDraweeController listener.
Controller id is passed to each of the listener methods which is useful for debugging and instrumentation purposes where those events can then be associated with a sequence. Subscriber is free to completely ignore this id, as late callbacks and other such correctness issues are taken care of by the controller itself.
